An Act implementing a home water filtration tax credit

This bill creates a tax credit for Massachusetts homeowners who install home water filtration systems when their public water supply is deemed unsafe by the state. Eligible homeowners can claim a credit equal to 60% of installation costs (up to $2,500 total), capped at $750 per tax year and $1,500 lifetime. The credit does not cover maintenance or filter replacements, and only applies to properties with public water connections where the water is officially classified as unclean or unsafe. The state environmental department will establish rules for administering the credit.
